One of the undead or the walking dead, an animated soulless corpse controlled by a voodoo deity. This state of being can come about due to prolonged exposure to kibitzing hoydens, hypocritical robots, and excessive sweating from time spent in the heat. Often a result of a strenuous marching band routine.

Dude, Brian has become such a zombie from all that marching band practice, just listen to him!

An organism in which at one point all biological processes had ceased, and afterwards had them reactivated (most commonly by the T-virus). These creatures hunger for the flesh of the living but do not generally need it to survive. When a living organism is found, other than a plant species, multiple zombies will gather, increasing their chances for a meal. Zombies are completely inert to each other, in any situation. Zombies are also not limited to human type and can infect other types of animals, and quite rarely, plants. Zombies generally have a longer life-span than their non-zombie counterparts as it is the nature of that which brought them back to life to keep them alive.

These zombies are interesting creatures, look how the mindlessly move toward their prey!
